Overidding dj-rest-auth Registration Serializer

I am trying to override the register serializer, I want to add a name field but the default view still shows

this is my configuration in settings.py

ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_EMAIL_VERIFICATION = 'none'

REST_AUTH_REGISTER_SERIALIZERS = {
    'REGISTER_SERIALIZER': 'accounts.serializers.CustomRegisterSerializer'
}

my url looks like this

urlpatterns = [
    path('', include('dj_rest_auth.urls')),
    path('registration/', include('dj_rest_auth.registration.urls')),
  ]

while my serializer

from dj_rest_auth.registration.serializers import RegisterSerializer

class CustomRegisterSerializer(RegisterSerializer):
    name = serializers.CharField(max_length=100)
    email = serializers.EmailField()

    class Meta:
        model = get_user_model()
        fields = [
            'name',
            'email' 
        ]

Have you tried REST_AUTH instead of REST_AUTH_REGISTER_SERIALIZERS?

REST_AUTH = {
    'REGISTER_SERIALIZER': 'accounts.serializers.CustomRegisterSerializer'
}
